Marine Hot Water Tank Application
The marine hot water tank series is designed for vessels with AC power supply (380V/50Hz or 440V/60Hz), providing on-demand hot water for:
-
Crew showers & sanitation
-
Galley & laundry use
-
General shipboard hot water requirements
Working Principle
-
Integrated Fresh Water Supply
-
Connects directly to the ship’s pressurized freshwater tank
-
Water flows into the heater for controlled heating
-
-
Smart Temperature Regulation
-
Thermostatic Control (45°C–65°C):
-
Heating activates when temperature drops below 45°C
-
Heating stops at 65°C to prevent scalding & save energy
-
-
-
Safety Protections
-
Low Water Cutoff:
-
Auto power shutoff if water level falls below safe limits
-
Prevents dry firing & protects heating elements
-
-
Pressure Relief Valve:
-
Ensures tank integrity during pressure fluctuations
-
-
